Conformity with other industrial standards: RINF/RSM/RailML

[MathiasVDA]

In Railway, several open standard vocabularies already exist.

RailSystemModel (semantic model under construction):

RailML (semantic model under construction):

RINF:

FYI, semantic model of RSM (1on1 copy of UML model) and several others are also available here:

I see a lot of classes that are more narrower defined in the mobility vocabulary. Certainly when dealing with topology (network, point, ...). It would benefit the whole transportation sector, to not invent ANOTHER standard that is again slightly different.

For example: RSM has been developed for many years by many different infrastructure managers and (light) railway undertakings. A lot of knowledge and thought has been put into the best modelling possible. The current mobility standard might be sufficient for the use case you have in mind but might not be for future use cases. In order to be more future proof and gain a larger audience, it would serve to link ontologies together, like you want to link organisations together.

Maybe a better ressource to compare your ontology with is the Siemens developed ontology RTO (https://siemens.github.io/ProductConfigurationWithSHACL/topo/v1.0/index-en.html) which is based on RTM, which is in its turn the predecessor of RSM.
